Here, the finely powdered bagasse ashes are used as a partial replacement of cement in concrete and compared it with conventional concrete. In this work, the mechanical and durability properties of concrete with bagasse ash which is partially replaced with cement (5%, %, 5% to weight of cement) additional to it sugarcane fiber is also added (.5% and % to weight of cement) is studied. The physical and chemical properties of the collected samples are determined. The hardened concrete specimens were subjected to compression and tensile tests after 7, and 8 days of curing. The durability of the concrete specimens to sulphate attack and acid attack are tested. The concrete specimen in which the bagasse ash is partially replaced with cement showed higher values of compressive strength and tensile strength when compared to that of conventional concrete and the durability of the concrete specimens were found to be similar to that of conventional concrete. INTRODUCTION The main problem in construction industries is unavailability of construction materials, on the other side the main environmental problem is industrial waste. In the experimental study, an attempt has been made to use the bagasse ash in concrete. Instead of disposing, the industrial waste can be recycled and used in the construction process. The attempt has been made to utilize the industrial waste of bagasse ash used as supplementary cement replacement materials. This work examines the possibility of using bagasse ash as a partial replacement of cement and natural sugarcane bagasse for new concrete. will be partially replaced as 5%, %, 5% and sugarcane fiber of.5% and % is added for each bagasse ash replacement concrete and tested for its compressive strength and tensile strength up to 8 days of age and were compared with those of nominal concrete. To improve the quality and reduce cost of material we can replace cement with bagasse ash (Srinivasan and Sathiya, ). Requirement for economical and environment-friendly materials has extended an interest in natural fibers like natural sugarcane bagasse have been utilized. These wastes should be disposed properly without affecting the environment as well as human beings (Apurva, et al., ). EXPERIMENTAL PROGRAMME Materials used This experiment includes the casting, testing and comparison of conventional concrete with cement being replaced with bagasse ash at 5%, %, and 5% by weight addition to it.5%.% of sugarcane fiber *Corresponding authors melchizedek5@gmail.com

It acts as a good pozzolanic material and can be used as an add-on for cementitiousmaterial (Inbasekar, et al., 6). The specific gravity of the bagasse ash used was.. The microscopic image of bagasse ash particle used and the chemical composition of the bagasse ash is given below (Fig. ). Sugarcane fiber It is a major food crop for tropics and subtropics. It is the important raw materials used for sugar production. Sugarcane bagasse is the waste produced after juice extraction from sugarcane. The Sugarcane bagasse ash is obtained as by product of control burning ofsugarcane bagasse (Abdulkadir, et al., ; Richard, et al., ). In this work sugarcane fiber which is used as an addition to increase the strength of the concrete (Table ). Mix proportions The mix design was carried out as per the method featured in (IS: 6, 9). The grade of concrete chosen was M5 and it was designed to obtain a target strength of.6 (N/mm ) at 8 days. The mix details are presented in Table. Compression strength Cube specimens of size 5 cm 5 cm 5 cm were casted for %, 5%, % and 5% particle replacement with cement and compared with conventional concrete. Universal testing machine (UTM) was used to calculate the maximum load (Fig. and ). The cube specimens were tested after 7, and 8 days of curing (Tables and ). Test for split tensile strength Cylindrical specimens of diameter 5 cm and height cm were used to determine the split tensile strength of the concrete. Universal testing machine was used to calculate the maximum load. The cylinders were tested after 7,, and 8 days of curing (Fig. and 5). The load is applied gradually till the specimen fails (Tables 5 and 6) (Kawade, et al., ; Ashish and Anupam, 5). Test for durability Chemical attack on concrete often leads to deterioration and results in the failure of the structure. Hence it is necessary to test the durability of the concrete against chemical reactions. Six cubes were casted for each specification of concrete. The Fig. FESM images of the bagasse ash particle.

CONCLUSION The From the results the following observations were made: (i) Concrete specimens with 5% of the cement aggregate replaced with bagasse ash showed an increased compressive strength of nearly % on its 8th day. (ii) The split tensile strength of the concrete replaced with bagasse ash showed similar results as that of conventional concrete. The concrete specimens were found to be durable when subjected to acid and sulphate attacks, which makes it suitable for construction. REFERENCES Abdulkadir, T.S., Oyejobi, D.O. and Lawal. A.A. ().
